Dear Mozilla Team,

I use Firefox as my default browser. MS Teams gives a failure message: "Your browser doesn't support audio". I have to use a phone for audio communication. How to correct this failure?

Regards Pentti Jussila

for some reason, right clicking doesn't show the fonts. so i have to guess where 'new tab' is or whatever. i switched my firefox and my computer to light mode and it still doesnt show. im not sure if the problem is a firefox setting [because youtube shows font when i right click a video but not in my home youtube page] or if it's my computer setting.

See the attached picture. Message box concerning purging deleted msgs is back after latest update. I want to be able to clear the trash manually. This just showed up after the latest update.

I have seen in the past that people were wanting to know the same thing, but following the solutions from back in time don't work because too many things have changed.

Sooooo, how do I turn this off ?

I am running 78.9.1 (32-bit)

I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!

I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.

Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!

I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!

Obviously, my FF is fully up to date!

Any comments!

This all started after last firefox upgrade/update a few weeks ago so installed gmail chrome which works fine.

Even reistalled OS & then worked ok till firefox did it’s own updae.

I have deleted & reinstalled a couple of times but same problem.

I use Linux Ubuntu 20.04.2LTS on an older (+/- 5 year) HP Pro 3130 MT a 64 bit machine. Chuck

After a monster update on Win 10 it uninstalled Thunderbird. After I reinstalled I find that I lost all local folders except junk, trash, and outbox. This is odd since my inbox reinstated undeleted email dating back to 2018. So I look thru Thunderbird support questions and can only find answers that predating TB v. 78.9.0 (64-bit). If you have an answer for me please be specific e.g. " go to help tab, click on troubleshooting" etc. if you get my drift.

If you want to feel sorry for me that's ok. I lost all bank/IRS stuff, genealogy correspondence, program warranties, and when I think about it I just want to sit down and snivel.

BTW it also ate my address book, but I can only deal with one thing at a time.

Please help, Peggy

Clicking a link in email from my insurance company always yields error 404, file not found. Saw notes from 2017 about removing all data about a domain but can not find a way to do that in current version. Clicked link today, 4/6/2021, got error "HTTP/1.1 404 Not Found" This has been happening for a long time. I have cleared cookies and all data, removed & reinstalled Firefox, still same issue.

Using Thunderbird Version 78.9.1, on Windows 10 20H2. I can no longer drag/drop an email contact from "All Address Books," "Personal Address Book," or "Collected Addresses," to any of my 12+ address lists. When I attempt to drag&drop, it places a duplicate contact in the source book instead of copying into the destination list. I'm not certain how long the problem has existed, the last time I needed to perform this task was about three months ago. I usually take upgrades as soon as they are offered.

What is the nature of the "Disconnect" agency whose solicitation appears as a tab page from Firefox requesting donations? Please explain who is "Disconnect." From the web address it is not clear what the connection is with Mozilla. What is the difference between donating via the "Disconnect" and donating via the route provided under the "about Firefox" menu item? Presumably "Disconnect" is servicing Mozilla, yet I am wishing that relationship and security to be clarified more convincingly before contributing by that route. Thanks for responses.

I keep getting a message saying that the sending of my password did not succeed.

I'm trying to add an existing account to my TB. I've to New, Existing account. Input all the correct Name, username, password. I keep getting the error message "Unable to login at server. Probably wrong configuration, username, password." Is there any support line I can call?

I'd like to search a folder for a named attachment, but I can't work out how to do it. When I select "Attachment" in the first column of the "Search Messages" window, no matter what I put in the second column (e.g., "is", "begins with") and no matter what I put in the third column (including the name of, or first letter of, an attachment known to be in the folder being searched), I always get the same result: "No matches found". A solution would be greatly appreciated as it is not an uncommon for me to need this kind of search. Thanks, Ian.
